To announce her arrival, the couple posted a photo of their growing family on Facebook along with a letter they’d penned for August, telling her that ‘childhood is magical’ and reminding her that she only gets to be a child once, ‘so don’t spend it worrying too much about the future.’

The fill her with all their hopes they have, explaining: ‘I hope you read your favourite Dr Seuss books so many times you start inventing your own stories’ and ‘I hope you run as many laps around our living room and yard as you want’.

With a slightly more tongue-in-cheek line, the couple even refer to their hopes that their latest family addition likes sleep: ‘And then I hope you take a lot of naps. I hope you’re a great sleeper. And I hope even in your dreams you can feel how much we love you.’

‘August, we love you so much and we’re so excited to go on this adventure with you.’

Mark and Priscilla’s firstborn, Max also received a letter the day she was born in 2015, which about the world they hoped to see her grow up in – a world with better education, fewer diseases, stronger communities, and greater equality.
